Application of Flipped Classroom Combined with PBL Teaching Method in the Teaching of Respiratory Intensive Care Unit Nursing

Objective:The aim is to investigate the application effect of flipped classroom combined with problem-based learning(PBL)teaching method in the teaching of respiratory intensive care unit nursing.Methods:100 fresh nursing students who were interned in the respiratory intensive care unit of our hospital from June 2020 to May 2022 were selected and randomly divided into 50 students in the control group and 50 students in the experimental group.The students in the control group were taught by PBL teaching method,and the students in the experimental group were taught by flipped classroom combined with PBL teaching method.After the completion of the teaching,the teachers combined the performance of the two groups of students,and scored them comprehensively in terms of their professional theoretical knowledge,clinical operation skills,independent learning ability,and teamwork ability,and carried out a survey of the experimental group’s students in terms of their satisfaction with the understanding of theoretical knowledge,clinical operation,independent learning ability,teamwork ability,and other dimensions.Results:There was no statistical significance in the specialized theoretical knowledge scores of the two groups of students(P>0.05).The scores of clinical operation,independent learning ability,and teamwork ability of the two groups of students were statistically significant(P<0.05),and all the scores of the students in the experimental group were higher than that of the control group.More than 90%of the students believed that the flipped classroom combined with PBL teaching method could assist in the comprehension of theoretical knowledge,improve the clinical operation skills,enhance the ability of independent learning and teamwork;there were 92%of the students supported the use of flipped classroom combined with PBL teaching in respiratory intensive care unit nursing teaching.Conclusion:In the teaching of respiratory intensive care unit nursing,the use of flipped classroom combined with PBL teaching method can improve the learning effect of students,and has certain value in teaching.

Adsorption of phosphate from the Yellow River water by desert particles:Kinetics and equilibrium studies

The equilibrium and kinetic adsorption of phosphate （P） from the Yellow River water onto desert particles taken from the Ulan Buh and Kubuqi deserts were investigated. Effect of the initial concentration of P and particulate matter on the sorption was ex- plored. The kinetic studies show that adsorption rate was faster within the 0-8th hour period, then gradually decreased at 8th-48th hour period and basically tended to a dynamic equilibrium at the 48th hour, but there exists an adsorption difference of P onto dif- ferent desert particles. The uptake process of P followed the pseudo-second-order rate model and the Morris-Weber diffusion equation which indicates that the adsorption process was mainly controlled by P diffusion inside the particles. The equilibrium in- vestigation obtained an adsorption-desorption equilibrium mass concentration （EPCo） of P from the Yellow River water on desert particles with the range of 0.010-0.042 mg/L, which is higher than present P concentration in the Yellow River. This study indi- cates that desert particles entering the river might release P to the Yellow River.

经皮冠状动脉介入治疗患者术前访视需求的调查研究

目的了解经皮冠状动脉介入治疗患者术前访视需求并分析其影响因素。方法采用自制问卷对贵阳市2所三级甲等医院271例择期经皮冠状动脉介入治疗的患者进行调查。结果经皮冠状动脉介入治疗患者术前访视需求总分为(145.76±21.20)分,相关费用维度得分最高,其次为心理支持维度,环境信息和手术过程维度得分最低。多元线性回归分析结果显示,文化程度、居住地和医保类型是经皮冠状动脉介入治疗患者术前访视需求的影响因素。结论经皮冠状动脉介入治疗患者总体上对术前访视有较高需求,其中相关费用、心理支持需求尤为强烈。建议护士根据患者具体情况及需求给予个性化、多元化的术前指导及心理干预,降低患者应激反应,提升患者就医感受。

剖宫产术后再次妊娠孕妇阴道试产决策求助体验的质性研究

目的深入探讨剖宫产术后再次妊娠孕妇阴道试产决策的求助体验,为制订满足其阴道试产决策援助需求、促进其阴道试产、增进母婴健康的策略提供参考。方法运用现象学研究法,选取2017年12月—2018年2月在贵阳市某三级甲等医院住院的14名剖宫产术后再次妊娠孕妇进行深度访谈,并运用Colaizzi分析法对访谈资料进行分析、总结、归纳。结果提炼出剖宫产术后再次妊娠孕妇阴道试产决策求助体验的3个主题:决策援助需求、寻求决策援助的途径及体验、理想的决策援助方式。结论剖宫产术后再次妊娠孕妇阴道试产决策时,希望得到专业意见、情感支持和知识方面的决策援助,医护人员应关注其决策援助需求,提供便利、专业性、个性化的医疗服务,帮助其正确看待阴道试产,增强阴道分娩信心,避免盲目选择再次剖宫产。
